I saw something I've never seen before today. The Freud 8" reversible stacked finger joint blade kit. It is essentially just the two outside blades of a stacked dado set, no chippers and no shims, but the blades have offset carbides and make a 1/4" kerf stacked A-B-arbor or 3/8" kerf stacked B-A-arbor.
Let me see if I can find a link. Here they are on Amazon. The local store I saw them at has them at $10 less then Amazon. Maybe I'll go back Friday and spend some overtime money.
I wonder what rake angle these guys are? For that matter, do I go to Freud or Bosch website for more info? Aha! The Freud website still has some info. Rake appears to be 20 degrees (also called hook angle). A bit much for pull operation of the RAS (I don't like going above +5 degrees and won't do pull cuts above +15 degrees - in fact, I think +15 degrees is the most aggressive hook angle blade I own), but pushing and ripping modes of operation should still be ok.
So, I answered my own question about hook angle. Does anyone know what sorts of conditions should be avoided to avoid unevenly stressing the offset mounted carbides?
Thinking about this more, I think I may just have thought myself out of the purchase. I started thinking that since this is essentially an FTG grind that it wouldn't be good for crossgrain dadoes, but might be ok to use to cleanup the bottom of a 1/4" or 3/8" dado cut just under depth using the stacked dado set. Then I got to thinking that I have 1/4" and 3/8" router bits (straight) and could just cleanup said under depth cuts on the router table. That led me to thinking that maybe I should get one of those tenoning jigs to use on the router table instead.
Has anyone used tenoning jigs on the router table? What sorts of things have you used them for? Would you buy a tenoning jig just for the router table if you didn't have a table saw to use it on?
Trying to figure out the best way to spend my overtime money from last week is harder then I thought. Guess that means I'm just about done with tool collecting and it is time to get my back healed up and make stuff.
